9NEWS reporter Simon Bouda has paid an emotional tribute to his grandfather on Anzac Day, describing his heartbreaking personal journey to visit the WWII pilot's final resting place in Papua New Guinea.

Bouda, reporting live on the Kokoda Campaign commemorations, fought back tears as he told TODAY's Karl Stefanovic about his trip on Monday to Bomana War Cemetery in Port Moresby.

Bouda's grandfather, Flight Lieutenant George Heads, died on June 7, 1944 during WWII when the plane he was flying crashed in Milne Bay, PNG. He was 33 years old.

"I took the opportunity when I was assigned this particular job to go and visit his grave site," Bouda said this morning from the Isurava memorial site.

"It was heartbreaking … You just think about those guys, you know, they gave so much … It's hard."

"I took his medals, I took the telegram his wife, my grandmother, received to notify her he had died," he said.
